Inside the broken down paper mill,  Sam,  Cas and Dean were hunting a hive of vampires. "Sam,  over here! " Said Dean.  Sam walked over to Dean and looked at where he was pointing. "What is that? " He asked. It was a small piece of metal on the dusty floor.  " I don't know. " Dean walked over and attempted to pick it up. "What the-" The trapdoor swung open under Dean. "Shit!" Dean grabbed the sides of the opening. "Sam,  Cas,  come and help me you dipshits! " Dean yelled.  Sam and Castiel ran over and pulled him up.  "Those damn bastards put traps! " Sam walked over to the opening.  " I can't see the bottom. " He called over his shoulder.  Cas and Dean joined him.  He lit a match and dropped it.  It fell until he couldn't see the light anymore.  "That is deep." Sam turned to Dean.  " No more picking up shinies,  Dean. " He mocked.  " Bitch.  "  " Jerk. "  
The three walked to towards the back of the house.  "Do you hear that? " Cas whispered.  They heard a tapping noise coming from under them.  "There are those sons a bitches! " Dean whisper-shouted.  "Dean,  over here! " Sam quietly called.  Dean walked over to Sam and found them both standing around the top of the steps leading to the basement door. "I'll go first, you two watch my back. " Dean murmured.  They nodded,  and Dean slipped down the stairs,  Cas and Sam following suit. With Sam and Dean's guns pulled,  Dean kicked down the door.
